The example in this article describes the simple implementation method of PHP's ajax technology based on jquery to transfer json data. Share it with everyone for your reference, the details are as follows:

html page:

<html>
<head>
<meta http-equiv="content-type" content="text/html;charset=utf-8" />
<script type="text/javascript" src="jquery-1.8.2.min.js"></script>
<script type="text/javascript">
 $(function(){
   $("#send").click(function(){
    var cont = $("input").serialize();
    $.ajax({
      url:'ab.php',
      type:'post',
      dataType:'json',
      data:cont,
      success:function(data){
       var str = data.username + data.age + data.job;
       $("#result").html(str);
    }
  });
 });
 });
</script>
</head>
<body>
<div id="result">一会看显示结果</div>
<form id="my" action="" method="post">
 <p><span>姓名：</span> <input type="text" name="username" /></p>
 <p><span>年龄：</span><input type="text" name="age" /></p>
 <p><span>工作：</span><input type="text" name="job" /></p>
</form>
<button id="send">提交</button>

php page:

    $username = $_POST['username'];
    $age = $_POST['age'];
    $job = $_POST['job'];
    $json_arr = array("username"=>$username,"age"=>$age,"job"=>$job);
    $json_obj = json_encode($json_arr);

Use post method

<script type="text/javascript">
 $(function(){
 $("#send").click(function(){
   var cont = {username:$("input")[0].value,age:$("input")[1].value,job:$("input")[2].value};
   var url = 'ab.php';
   $.post(url,cont,function(data){
    var res = eval("(" + data + ")");//转为Object对象
   var str = res.username + res.age + res.job;
  $("#result").html(str);
  });
 });
 });
</script>
